Yaak is a local-first desktop API client for sending requests, debugging APIs, and collaborating through Git. It runs on Linux, macOS, and Windows, and supports HTTP/REST, GraphQL, gRPC, WebSocket, and server-sent events. Users can arrange requests in workspaces and folders, switch environments, and reuse authentication and variables. Directory sync stores requests, folders, and environments as individual YAML files for Git workflows.

Yaak imports work from Postman, Insomnia, Bruno, OpenAPI, and curl. Plugins support authentication, importers, and template functions, with a 1Password plugin for retrieving passwords. The desktop app stores data locally and sends API requests directly to chosen servers; it has no built-in analytics or tracking. Optional workspace secret encryption uses XChaCha20-Poly1305, with the master key protected by the operating system keychain. Free use is for personal purposes; commercial use requires a license. Individual Annual costs $79 a year, and a 30-day trial is available.
